for producing pleasant and decorative lighting effect.

These and other objects of the invention will be apparent from the ensuing description and the appended claims.

One form which. the invention may assume is exemplified in the following description and i1- lustrated by way of example in the accompanying drawings in which:

Fig. 1 is a view, partly in section and partly in elevation of the sprinkler of the invention.

Figs. 2 and 3 are sections taken along the lines 2-'-2 and 3-3 respectively of Fig. 1.

-'Fig. 4 is a vertical sectional view on a larger scale, taken along the line 4-4 of Fig. 1, showing certain details of construction.

Fig. 5 is a plan view of the spr-lnkleiz,

Fig. 6 is a section through one of the jet nozzles, taken along the line 6-4 of Fig. 5, showing the manner in which it is adjustably mounted on the sprinkler.

Referring now to the drawings, there is shown a sprinkler generally designated as H), including a base H having legs I2 and a body portion l3. A tubular member I4 is also provided comprising an upper vertical portion [5 and a lower, right angular portion l6 which is in threaded engagement with the upper portion at IT. The tubular member 14 passes through the body portion I3 of the base and may be clamped in adjusted position by means of a set screw I8. A hose l9 may be coupled to the lower end of the tubular member I4, and a rigid conduit is provided, such conduit passing upwardly through the tubular member l4. The conduit 20 is welded to the tubular member 14 at 21 and it is spaced and centered by means of fingers 22. A plug 21 is provided at the lower end of conduit 20 for coupling to an extension cord 28.

A bowl shaped reflector 30 is mounted at the upper end of the conduit 20 and is covered by means of a glass cover 3|. As shown in Fig. 4, a metal coupling member 32is in threaded engagement at 33 with the upper end of the conduit 20 and at 34 with the reflector 30. A Bakelite or other suitable non-conducting insert 3 Claims. (01. 299- 4)? necting leads 40 are soldered at 46 to the leads is provided, being keyed to the coupling member 32 at 36 ,and having a threaded socket 31 formed therein for," reception of an incandescent globe 38. The Bakelite insert 35 is provided with a solid tail or extension 39 which is received within the conduit. 20. The tall 39 is drilled longitudinally to provide separate, insulated passages 40 for reception of connecting leads 4!. The lower ends of the leads 4| are spaced apart by a tongue 45 f rmed on the Bakelite insert, and the con- 41 Of a cable 48, the other end of which is connected to the plug 21. The upper end of one of the connecting leads 48 is soldered to a contact button 49 and the other lead 40 is pressed against the threads of the socket 31. v

It will'thus be apparentthat an easily assembled structure is provided for establishing electrical contact between the plug 21 and the electric globe 38, that the electric leads and the interior of the bowl 30 are sealed against access of water and that the leads and contacts are insulated from one another.

Referring again to Fig. 1, a revoluble casing 52 is provided on which a'glass or transparent plastic dome 53 is mounted as by means of screws 54 and a clamping ring 55. The casing 52' is revolubly mounted upon the tubular member M in the following manner. An outer collar 6| secured to the bottom of the casing 52 by means of screws 62, is provided with an inside flange 63. Upon the collar 61 is seated an inner collar 64, which is supported by and is revoluble upon a flange 65 formed on the tubular member [4. A water-tight seal is provided by means of a gasket 66 pressed against the periphery of the tubular member 14 by means of a coil spring 61, and the assembled parts thus described are clamped in place by an externally threaded nut or washer 65a and an internally threaded nut 66a.

In its upper portion the dome 33 is provided with a tubular spike 61, as illustrated, and a decorative, multi-colored cap 68 is seated on the upper portion of the dome 33, being held in place by means of the spike 61.

Any desired number of jet arms 69 are provided, each jet arm comprising a tubular member 10 which is curved at 1| as illustrated. Each jet arm 69 is provided with a tip 12 and at its base 13 it is of larger outside diameter and is provided with a shoulder 14. A tubular connecting piece 15 is provided, being in threaded engagement at 16 with a radial opening 11 formed in the casing 52. The tubular connecting piece 65 is provided with a shoulder 18 and it is threaded at 19. The

outer end of each connecting piece is slidably received within a, jet arm 69, and to secure these elements in place and to allow adjustment of the vertical pitch of the jet arm, an expansion spring 80 and threaded cap 8| are provided.

It will thus be seen that, by screwing a connecting piece 15 into a radial opening 11, inserting the end of the connecting piece in a jet arm 89, and screwing the cap 8| inwardly against the compression of spring 80, the jet arm 69 will be firmly locked in place. The pitch of the jet arm is readily adjusted merely by turning it manually It will thus be apparent that a sprinkler is provided which is simple in design and dependable in operation and which provides a pleasing lighting eifect. The lighting unit is effectively sealed from the water and is non-rotatable. The jet arms are adjustable to throw the water at any desired angle above or below the horizontal plane. Thus, the sprinkler of my invention combines features contributing to mechanical efiiciency and an ornamental, pleasing visual effect.

While I have shown the preferred form of my invention, it is to be understood that; various changes may be made in its construction by those skilledin the art without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A sprinkler comprising, a base, a first tubular supporting member extending upwardly from said base, a housing rotatably mounted on said first tubular supporting member and including a translucent portion through which light may pass, a stationary lamp within the housing, a second tubular supporting member disposed within, fixed to and supported .by said first tubular supporting member and having the lamp mounted on the upper end thereof and having its lower end passing through the wall of said first tubular supporting member, means for connecting a water supply conduit to said first tubular supporting member, and electric leads within the second tubular supporting member and connected at one set of ends to the lamp and at the other set of ends to a plug on the lower end of said second tubular supporting member.

2. A sprinkler comprising, a base, a first tubular supporting member extending upwardly from said base, a housing rotatably mounted on said first tubular supporting member and including a translucent portion through which light may pass, a stationary lamp within the housing, a second tubular supporting member within the first tubular supporting member and having the lamp mounted on the upper end thereof, means fixedly connecting. the tubular supporting members together, means for connecting a water supply conduit to said first tubular supporting member, and electric leads within the second tubular supporting member and connected to the lamp for supplying the same with current.

3. A sprinkler comprising, a base, a first tubular supporting member extending upwardly from said base, a housing rotatably mounted on said first tubular supporting member and including a translucent portion through which light may pass, a stationary lamp within the housing, a second -;tubular supporting member within the first tubular supporting member having the lamp mounted on its upper end and having its lower end secured, to and'passing through the wall of the first tubular supporting member, means connectinga water supply conduit to said first tubular supporting member, and electric leads within the second tubular supporting member connected to the lamp for supplying the same with current.
